Question

find the area of shaded portion? ​

Answer 1

First figure:-

Area of horizontal path - area of vertical path = area of shaded region

(2×7.5) + (1.5×5) = Area of shaded region

15 - 7.5 = Area of shaded region

Area of shaded region = 7.5 m²

Figure 2:-

Area of shaded region = Area of square - ( Area of vertical path + Area of horizontal path (excluding the common area from this)

Area of shaded region = (10×8) - (8×2 + (10-2)×2)

Area of shaded region = 80 - 32

Area of shaded region = 48 m²
